the vlan tagging idea is a virtualization of the PNI construct.
why use an IX when running 10's/100's/1000's of private network
interconnects will do?
granted, if out of the 120 ASN's at an IX, 100 are exchanging on
average - 80KBs - then its likley safe to dump them all into a single
physical port and vlan tag the heck out of it.
its those other 20 that demand some special care.
